This invention. relates to photographic film i splicing and moreparticularly to means forholding the severed portions of the film inposition-to be spliced..

Films of the con I quently,`l duel to coiling and/or their inherentfragility, develop cracls :and other defects with resultantiseparationof the'film into severed portions which effects interruption in thecontinuity of the projection of the picture. In order to lprecludeseparation during projection, the films are usually .inspected aftereach iprojection in order thatany defects may be detected and remediedprior torsubsequentprojection. To remedy any de'fects, one or more of:the picture frames of the film-or the areas containing the defectsare`severed and 'removed fromV the film and the remaining or severedportions of the film are'spliced together Vby .adhesively securingtheirsevered end zones in lapped relation.

To facilit'ate splicing of the film in a more .accurateandexpeditiousmanner, machines substantially automatic infoperation are employed. Amachine of this type is usually equipped with film Supporting-means orthe like on which the end sections of the severed .portions .of the filmto Abe spliced -are received, the means being protfdedl with spacedplates having groups of pins and defininga `slot therebetweenlover whichthe end zones oftheend sections extend and through which slota-device isoperated to `condition and The-pins extend into sections...of severedfilm portions, adjacenttheir end zones, to secure the end sections inlapped relation and maintain the .propervregistry of the pictureframesand perforations of the respective B'nd ZOnES.

i Obviously, extreme care must be taken toeifect ther correct. spacingand registry .of Vthe i picture frames andV perforationsvof the endzones when they are initially. positioned on the plates in lapped.relation for splicing.

` .1 `Inasmuch`` as .some film has .an inherent tendency to coil orbuckle when positioned in the .ma- China,- and. in instances `where thefrictional -engagement :of the pins .with the film; isinsuficient tomaintain it in adjusted position, it canbe readily understoodthat when,the fingers of. the operatr are :removedffrom onetof the end vsectionsto permitand effect closingI ofthevgate, an interval otis `thus .madeavailable wherein` theend section released will ;coil orbuckle away fromthe plate and .the other section, therebyv necessitating oneormanyrearrangements. ofthe released sectinuous movingstrip .type fretioninto proper position before the gate; can be closed and the machineoperated. Obviously, coiling'or displacement of the film previouslto the'closingof the gate establishes a cumbrous condition with attendantlossV of valuable time.V

The present invention aimsto precludethe foregoing deseribed coilinfr ordisplacement of the film, it being one of the objects thereof to providea device or film holder for maintaining vthe film in position forsplicing in a manner to permit removal of the fingers from the film,whereby the gate may be closedi'to hold the fihn upon the platesduringhsplicing'.

Another object is t'o provide a film holder of theI foregoing' describedcharacter which is equipped With film holding meanslatchably retained inengagement with the film to secure the same against 'displaceinent'previous to and .during the closing of the gate.

Another object is to provide a film holder of the foregoing describedcharacterswhereinV the film holding'means orfingerr is operatedl `out offilm holding'positio'n 'by the gate when the. latter is so operatedthereby facilitating quick removal of the spliced film from the machine.V

Anotheriobject isv to provide aldevice of the foregoing describedcharacter sofconstructed and arranged `as to be readily attachedtofllin` splioing machines already inuse and-without substantiallymodifyingthe machinesf 4 A further object is to provide a. film holderof the foregoing describecl character which is simple in-constructionand Ie'conomieal in manufacture, durable in use, eflicientwin Operation,andwhich is' easily assembledin combination with anlm splicing vmachinefor operation therewith.

Figure is a longitudinal, sectional view of the structure illustrated inFigure 1, showing the gate and film holder disposed in engagement withthe severed end portions of a film.

Figure 6 is a disassembled perspective view of the film holder.

With reference to the drawings, and more particularly to Figure lthereof, there is illustrated a portion IO of a. film splicing machineequipped with a film Supporting bed or means H comprising right-hand andleft-hand film receivingV piates |2 and l3 provided with groups of pins|4 and l5, respectively. The bed is formed with a transversely extendingslot IS laterally defined by the plates and through which a plurality oftools or the like (not shown) are operated for conditioning and splicingthe film upon operation of the machine.

The bed or means H has mounted thereon Va frame i'l which embraces theplates |2 and l3, the-plate lv3 being movable towards and away from'theplate |2 for shifting a section offilm as hereinafter made apparent. Theplate l2 is provided with a hinge member l8 having a pair of spacedbearings IG through which extends a pintle or shaft to which is fixed apair of lugs 2! of a film holding gate or means 22. Between the bearingsIB, the pintle has sleeved thereon a coil spring 23 having one endconnected to the, gate and the other end to the pintle and which springfunctions to urge and maintain the gate in open position for a purposehereinafter made apparent. The gate is provided with a latch 24 whichextends through a keeper slot 25 in thepplate l2 and latches the gate,under ten- `sion of the spring 23, to the bed in film holding positionover the film, the latch being automatically operated upon terminationof the splicing of the film to release the gate and thus efiectautomatic Operation of the gate to open position by the spring 23.

, As shown in Figures 1 and 5, the gate 22 is equipped with a laterallyprojecting arm or bridge member 26 which extends over the slot i5, themember being provided with a shoe 21 for engaging film disposed on theleft-hand film receiving plate l3 when the gate is in closed position.The face of the gate, adjacent the plate [2, isslightly modified andljoined with a transverse channel 28 for a purpose hereinafter morefully disclosed. The plate 13 is shiftable towards and away from theplate l2 for shifting the secgtion of film retained thereon with lappedrelation with the section retainer on the plate |2 as hereinafter madeapparent. Inasmuch as the foregoing described parts of the machine form.no part of the present invention per se, a more detailed disclosure ofthe same is not believed necessary.

For cooperation with the gate 22, there is provided means 34 (Figures 2,3, 4 and 6) for initially retaining the film comprising a tubular memberor sleeve 35 rotatably mounted on the spring 23 and formed with a flatface 35 having attached thereto, by means of a screw 37, one terminalpart 38 of a spring finger 39, the opposite terminal part 40 of thefinger being disposed in angular relation with the end 38 and within'the channel 28 of the gate when the latter is in closed position asillustrated in Fgure 4 of the drawings.

The gate is provided with a seat 4l on which is secured, by means of ascrew 42, one end section of a leaf spring 43. The opposite end section44 of the. leaf spring 43 extends over. the

4 sleeve 35 and'is formed with a detent 45 for seating into alongitudinally extending slot 45 formed on the circumferential face onthe sleeve 35. The slot 46 accommodates the detent 45 to 5 latch thefinger 39 to the gate when the gate and finger are in film holdingpositions as illustrated in Figure 4, thus eifecting unitary Operationof both the finger vand gate to open positions as illustrated in Figure2. f I 10 In Operation, the gate 22 and finger 39 being in the openpositions shown in Figure 2, the fingers of both hands of the operatorare employed to manipulate and position the end section 5l of theright-hand severed portion 52 of the film 53 upon the right-hand filmreceiving plate |2 with the pins l4 extending through the usualperforations of the section 51 (not shown). When the section 5! is thuspositioned upon the plate l2, the fingers of the operator's left andright hands serve to hold the end zone and the adjacent` zone of thesection 51, respectively, against displacement, whereupon, the fingers'of the right hand are removed from the adjacent zone to operate thefinger 39 into closed or film holding position over the adjacent zoneand thus secure and maintain the section 5! against displacement, thedetent 45 of the spring 43 being disposed out of the slot 45 asillustrated in Figure 3.

When the section 51 is thus secured, the fingers of the left hand areremoved and Which fingers together with the fingers of the right handare employed to manipulate andposition the end section 54 of theleft-hand severed portion 53 of the film upon theleft-hand filmreceiving plate 13 in the same manner as described 'in connection withthe section 5|,and with the end zones of both sections in lappedrelation. When section 54 is thus positioned, the fingers of the righthand are removed from the end zone thereof and employed to operate thegate to closed or film holding position overv thefinger .39 and entiresection 5l, the' shoe 21 serving to hold the end zone of the section 54.

When the gate is thus closed; the iingers` of the left hand are removedfrom the section. 54 and the machine operated for splicing 'and in amanner wherein the tool means are sequentially actuated to skive theemulsion-from. the emulsified surface of the end zone of the end sectionnearest the skiving tool; transversely cut both end zones immediatelyand laterally adjacent the aforementioned skived surface to dispose theend faces thus formed -in substantially registering 55 and abuttingrelation; move the plate l3 away from the plate l2 to longtudinallyshift the section 54 away from the section 5l to space their confrontingend faces in a manner to confine an application of adhesive solely totheskived'surface; apply the adhesive to the skived surface;

move the plate l3 towards the plate l2 toreshift the section 54.to.dispose its end zone in spaced, lapped relation' withv the end zone ofthe section 5i' and with the adhesive coated surface between the lappedzones, and apply pres- Sure to the lapped ZOnes to secure them togetherto form aclap jointI and thus 'complete the splic- When the severed end'portions of the film are spliced as heretofore described, the gate isautomaticallyoperated to open position,. and, inasmuch as the finger 39is latched to the gate, as illustrated in Figure 4, it is also operatedto open position with the gate, as illustrated in Figure 2, thuspermitting expeditious removal of the Jan. 21, 1947.
